ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...

Improving crop yields are essential to meet the increasing pressure of global food demands. The loss of high quality land, the slowing in annual yield increases of major cereals, increasing fertilizer use, and the effect of this on the environment all indicate that we need to develop new strategies to increase grain yields with less impact on the environment. One strategy that could help addres...

In vitro incubation studies were carried out to determine if various carbohydrase preparations contained appropriate activities to target nonstarch polysaccharides (NSP) of wheat, soybean meal (SBM), canola meal, and peas. Triplicate samples (0.1 g) were incubated with a number of carbohydrase preparations (i.e., cellulase, pectinase, xylanase, glucanase, galactanase, and mannanase) or their co...

ABSTRACT- Crop rotation has many benefits for agro-ecosystems production. In order to evaluate two current rotation systems of wheat (Triticum aestivum L.) production in Kamalabad region of Fasa, an experiment was conducted during 2015-2016 growing season. The rotation systems were fallow-wheat and cotton (Gossypium spp.)-wheat. Research plots were arranged as a randomized complete block design...

Cover crops can improve soil health by maintaining organic carbon (SOC) and nitrogen (N) contents, yet their dynamics in relation to crop yield a semi-arid cropping system are poorly understood. The main objective of this study was evaluate the response diverse winter cover species mixture on SOC N fractions relationship with sorghum (Sorghum bicolor L. Moench) wheat (Triticum aestivum L.)–sorg...

to evaluate the effect of crop rotation on spatial dynamic of fumaria vaillantti and polygonum aviculare a study was conducted at the three farms with different rotation in the astan ghods razavi filed that located at 10 kilometers southeast of mashhad, iran. the rotations were alfalfa- fallow- wheat, canola- fallow- wheat, and wheat- fallow- wheat. at the crosses of 7×7 m quadrangular grids ne...

Crop rows oriented at a right angle to sunlight direction (i.e., east–west within the winter cropping system in Western Australia) may suppress weed growth through greater shading of weeds in the interrow spaces. This was investigated in the districts of Merredin and Beverley, Western Australian (latitudes of 31u and 32uS) from 2002 to 2005 (four trials). Winter grain crops (wheat, barley, cano...
